Title: Detecting method for leaking point of piping
Inventor: KAWASE AKIRA
IPC: G01M3/28
Filed: 1985-09-30
Abstract: PURPOSE:To find out a leaking point immediately, irrespective of the embedded condition of the leaking point by sealing inactive gas, etc., in a pipe once, next, absorbing from one edge of the pipe to form the air layer in the pipe, dividing the quantity of the inactive gas, etc., absorbed until the oxygen concentration starts to rise by the cross sectional area of the pipe, and calculating the distance from the absorbing point to the leaking point. CONSTITUTION:An inactive gas, etc., are sealed from a line 2 to the whole of the pipe, a pump 4 of an absorbing line 5 is used, the inactive gas, etc., sealed from the inside of a pipe 1 are absorbed, an air layer X is formed in the pipe 1 near a P point, the absorption is stopped once and a valve G at the end edge is opened. Simultaneously when the absorption is restarted again and the absorbing quantity from the first continues to be measured by a flow meter 7, the oxygen concentration continues to be measured by an oxygen meter 6. When the oxygen concentration starts to be detected by the oxygen meter 6, the quantity of the inactive gas, etc., absorbed ever is read by the flow meter 7, and the absorbing quantity is divided by the cross section of a gas duct 1. Thus, the distance from the measuring point to the P point can be obtained.

Title: Differential decoding circuit
Inventor: NAKAMURA SATOSHI
IPC: H04L27/227
Filed: 1991-08-29
Abstract: PURPOSE:To reduce an error of reproduced data by using a subtractor means to apply difference calculation to an n-bit relative phase, discriminating the difference and applying Gray code conversion and parallel serial conversion to the result and reproducing the data. CONSTITUTION:A demodulator 1 extracts an n-bit relative phase for each one symbol timing and outputs the phase to a subtractor means 3. The means 3 applies differential amplifier calculation between an n-bit relative phase extracted in a current symbol timing and an n-bit relative phase extracted in one-preceding symbol timing to calculate a difference. A discrimination means 4 converts an output of the means 3 into a binary digital code by using a preset threshold level to reproduce the data. The data error is reduced even when the symbol is resident in the vicinity of I and Q axes by using a difference of measured phases of two consecutive symbols to reproduce the data.

Filed: 1984-10-17
Abstract: PURPOSE:To form a semiconductor laser crystal which includes a high density clad layer controlled in the thickness without meltback by providing a thin film meltback preventive layer between the clad layer and an active layer. CONSTITUTION:An N type Al0.4Ga0.5As meltback preventive layer 16 is formed in the thickness of 0.2mum between an active layer B and a clad layer 14. The layer 16 contains the same composition as that of the layer 14, Sn is used as an impurity instead of Te, and carrier density of 1.5X10<16>cm<-3> is provided for the additional amount of 30mg/1g Ga. The thickness of the other layers are 2mum for an N type Al0.4Ga0.6As clad layer 12, 0.15mum for an N type Al0.1 Ga0.9As active layer 13, 1.5mum for an N type Al0.4Ga0.6As clad layer 14, and 0.7mum for an N type GaAs cap layer 15. The meltback of the grown melt by adding high Te density is hardly melt back as the aluminum composition ration of the primary epitaxial layer is larger. Accordingly, when the same composition as the layer 14 is used as the meltback preventive layer, the meltback is hardly performed.

Title: Thermal analysis furnace for extremely high temperature
Inventor: ICHIHASHI MASAHIKO
IPC: G01N25/00
Filed: 1990-08-22
Abstract: PURPOSE:To prevent heat deterioration of an infrared ray and remarkably improve durability by making a double protective pipe structure comprising an inner protective pipe and an outer protective pipe provided outside the inner pipe with a distance to improve cooling efficiency by cooling gas. CONSTITUTION:Cooling gas supplied from a cooling gas supply source via a gas supply port 10 to each cooling gas passage 9 is sprayed from numerous cooling gas spray holes 11, 12 toward each halogen lamp 3 and flows toward an exhaust port 8 along an outer periphery of an outer protective pipe 7 while the gas is cooling the lamp 3. Thus, although the gas cools each lamp 3 and also cools the protective pipe 7, an inner protective pipe 6 made of alumina is prevented from coming in contact with the cooling gas by the protective pipe 7 and protected from thermal impact but applied only with infrared ray radiation energy, so that the pipe 6 is at a normal state of being heated by high temperature and also difference in temperatures between the inside and outside the protective pipe 6 can be maintained at a low level. As a result, uniform high temperature heating is possible.

Title: Power amplifying element protection circuit for high frequency power amplifier
Inventor: KOIDE JUNICHI
IPC: H03F1/52
Filed: 1989-08-25
Abstract: PURPOSE:To protect a power transistor(TR) effectively without a problem of excess protection by detecting a relation of phase between a collector voltage and a collector current of the power amplifier TR to prevent destruction of the TR due to the increase in the collector loss. CONSTITUTION:A resistor 4 is inserted between the emitter of a power amplifier TR 1 (in the case of a FET, a source) and ground, in general between the ground terminal of a power amplifier element and earth to detect a current flowing to the TR 1, and the phase of the current is compared with a reference phase. Then a phase difference between the collector (drain in the case of the FET) voltage and the collector current is detected and when the phase difference exceeds the setting criterion, a protection means is activated. Thus, a problem of overprotection is evaded and a problem of too late protection is eliminated.

Title: Input protecting circuit of cmos logic integrated circuit
Inventor: UENO NORIO
IPC: H03K19/003
Filed: 1984-10-19
Abstract: PURPOSE:To prevent the latch-up phenomenon of a CMOS circuit by providing a MOS transistor (TR) of diode connection, whose gate electrode and drain electrode are connected to the input terminal of the CMOS circuit in an input part and drain electrode is connected to a source power source, in an input circuit of a CMOS logic integrated circuit. CONSTITUTION:When a high-level signal is given from the driving side to a signal input line 6, this signal turns on N-channel TRs 5 and 2 of diode connection. This TR 5 permits the current flowed from the signal line side to a source power source VSS to pass through. At this time, a voltage drop Va is generated by the current flowed to a P-channel TR in the driving side. Consequently, the actual signal line input voltage is VDD-Va. When a low-level signal voltage is given to the input signal line 6, a P-channel TR 4 permits the current from the source power source VDD to the signal input line side to pass through. A voltage drop Vb is generated in this current by the current component flowed to an N-channel TR in the driving side. Consequently, the input voltage is VSS+Vb. That is, the signal level is compressed between VDD-Va and VSS+Vb.
